Question juridique clé
Whether the appeal met the formal requirements of Art. 42 BGG and could be considered.
Solution extraite
The filing did not contain a sufficient request or a legally adequate reasoning engaging with the cantonal court's findings, so it was not a valid appeal.
Motifs extraits
Art. 42 BGG requires requests and a reasoned explanation; the appellant failed to show, even in outline, how the lower court's findings were erroneous under Art. 97 BGG. He did not respond to the Federal Court's notice and correction opportunity.
